August will be another substantial patch month for Microsoft, with the vendor releasing 12 security bulletins next Tuesday to fix holes in both its Windows OS and the Office productivity suite.

Ten of the August 8 patches will affect Windows, with at least one rated as a "critical" update. The other two security updates, at least one of which also is rated "critical," affect Office. Critical flaws are those than can be exploited by attackers to run unauthorized code on a PC without any user action.

The patches, some of which will require a restart, will be released as part of Microsoft's regularly scheduled monthly security update, which security researchers call "Patch Tuesday." Microsoft's advance note on the updates discusses the issues.

More Coming on Aug. 8

Also on Tuesday, Microsoft will release an updated version of its Windows Malicious Software Removal Tool on Windows Update, Microsoft Update, Windows Server Update Services and the Download Center. The company also will release two non-security high-priority updates for Windows on Windows Update and Software Update Services.

Patch Tuesday has been keeping system administrators busy lately as the company has been responding to hacker attacks on unpatched flaws in its software, particularly a series of attacks on its Excel spreadsheet software.

Microsoft released seven patches in July, some of which addressed the much-publicized Excel bugs that Microsoft confirmed in June. System administrators also were busy with regularly scheduled monthly patches that month as Microsoft released 12 security updates.
